FASTENING DEVICE.

Application filed October 1c, 1911.

To all 207mm it may concern Be it known that I, BERNARD RINTEL SIM-MONS, a subject of the King of Great Britain, residing at 21 Vysestreet, Birmingham, in the county of Warwick, England, manufacturer,have invented certain new and useful Improvements in or Relating toFastening Devices, of which the following is a specification.

This invention comprises improvements in or relating to hat pin heads,buttons, brooches, badges and like articles.

In order that this invention may be clearly understood and more easilycarried into practice, I have appended hereunto a sheet of drawings,upon which Figure l is a side elevation of a hat pin constructed inaccordance with the present invention. Fig. 2 illustrates in elevationthe three parts thereof disassembled, viz. the cup-shaped body, thedome-shaped part, and the locking ring. Fig. 3 is a vertical sectionthrough the hat pin illustrated in Fig. 1. Fig. 4 is a vertical sectionthrough the locking ring. Fig. 5 is an inverted plan of the locking ringillustrated in Fig. 4:, showing same partly formed. Fig. 6 is a verticalsection through the cup shaped body. Fig. 7 is a plan of the cup shapedbody shown in Fig. 6.

In this invention which is shown only as a hat pin band a cup-shapedbody A is pressed up from sheet metal, said cup-shaped body having threeor other suitable number of projections a standing out from theperiphery of the cup. Said cup or body is provided with a shank a in thecase of a hat pin or button, or other suitable means of attachment.

A dome-shaped part B is arranged to lie inside the cup or bottom A andis stamped up from sheet metal, the outer face being convex and theinner concave. Said dome is incorporated to accommodate a piece oftextile material C so that in the case of a hat, a piece of the materialwith which the hat is trimmed can be inserted in the hat pin so as toharmonize with the trimmings.

The textile material is placed over the outer face of the dome B and theremainder of the material is twisted up so as to draw the material tightover the outer face, the material thus twisted lying in the chamberintermediate the concave face of the dome B Specification of LettersPatent.

and Fig.

The dome B is held in position by a looking ring D with a quickdetachable fastening, said ring being pressed up from sheet metal. Theperiphery of the blank is formed with two, three or more eccentric parts(Z between each of which a recess (Z is cut, said recesses correspondingto the projections a formed in the back A aforesaid. The blank is cuppedat CF and the eccentric parts d subsequently rolled or turned inward insuch a manner as to form resilient inclined guides 6Z while the recessesintermediate these guides form slots for the entrance of the projectionsa By these means the locking ring D may be attached to the bottom A in avery rapid manner as it is only necessary to place the two partstogether and partially rotate same relatively to one another when theprojections (1 engage the inner edge of the inclined guides (1* and lockin the manner of a bayonet joint. The outer face of the locking ring isprovided with a hole d through which the textile covering C on the domeis visible, the diameter of the said hole (Z being less than thediameter of the dome B so that the locking ring presses on the convexface of the latter and securely holds it in position.

It will be obvious that when it is desired to change the material C itis merely necessary to rotate the locking cap Dwithdraw same, remove thedome B and replace the textile material thereon with another piece,replace the dome B and locking cap D when the operation is complete.

It will be obvious that instead of using a dome covered by textilematerial, miniatures, etc., can be placed in the pin brooch or the like.

What I claim as my invention and desire to secure by Letters Patent isIn a fastening device for an article of the class described, thecombination with a hollow front plate having a rearwardly roundedperipheral portion and adapted to support an ornamental fabric coveringhaving its free margins folded behind and into the hollow of said plate,a band having a gripping portion reduced in size with respect to therounded peripheral portion to frictionally grip and stretch the fabrictightly over the outer face of said plate as the band [3518 back of thecup A as illustrated in is forced'rearwardly thereabout, and a cupuponrelative rotative adjustment of said shaped base closing the rearportion'of said cup and band, substantially as described. 10
